Answer:
The probability that a randomly selected subject in the state plays the guitar is:
0.21
Stepbystep explanation:
Let 'x' be the number of male.
Now it is given that 21% of males play the guitar.
That means 21% of x play the guitar.
i.e. 21%×x play the guitar.
Hence, the probability that a randomly selected subject in the state plays the guitar, given that the subject is male is calculated as:
Probability=( number of male members playing the guitar)/(Total number of males)
Probability=0.21
Hence, Probability is 0.21
